I fell down the stairs a couple weeks ago, and kind of skidded down them on my buttocks. I got a huge bruise across my left hip and buttock, like 10 inches long two inches wide in the shape of a smile, the bruise is completely healed and there is only pain if I apply pressure. However, where the bruise was I now have a large indentation. Its very and noticeable, will this go away?'??
